OK. You haven't ever said what you are trying to do with current vs previous frame data. I don't recall anyone ask for this specific requirement before. The OSG community have been around quite a long time now... So you are either doing something very novel or a trying to solve a common problem in a very awkward way. One thing to also considering in your pondering is that not all objects will actually be in the view frustum over subsequent frames, especially as you pan around, new objects will appear in the view frustum for the first time so won't have a previous modelview matrix associated with them. Since you haven't said what this is all in aid of I can't say whether this later issue has any baring, it will however, if you really need to do what you say you need to do will introduce it's own set of issues.
